Our first year on our pond, we stocked 30lbs of tilapia from BoatCycle in Henderson, TX and it was the cleanest our water has ever been. We keep talking about stocking again but I’m a little concerned it’s too late in the season for them to be effective. I think they survived into early November, but definitely eventually bit the dust. Toward the end of the season we caught several 2lb tilapia, and the biggest we stocked would fit in the palm of your hand!
